Lewis Dot Structures How to:1)Write down configuration 2)Draw the structure (each valence e-gets a dot) Neon:(1s)2(2s)?(2p) valence level“n”is2 2+6=8 electrons on the valence level So Ne gets 8 dots: :Ne: Fluorine:(1s)2(2s)2(2p)5 What if we put 2 fluorines together? n=2 :F·+.F :F:F: 2+5=7 valence electrons for F Look！They both have8 So F gets 7 dots: electrons:so we predict F,is a stable molecule V-52 + 5 = 7 valence electrons for F So F gets 7 dots: Lewis Dot Structures How to: 1) Write down configuration 2) Draw the structure (each valence e– gets a dot) Neon: (1s)2 (2s)2 (2p)6 valence level “n” is 2 2 + 6 = 8 electrons on the valence level So Ne gets 8 dots: Ne Fluorine: (1s)2 (2s)2 (2p)5 n = 2 F What if we put 2 fluorines together? F + F F F Look! They both have 8 electrons: so we predict F2 is a stable molecule V-5
